A 22-year-old man was in a motorcycle accident with resultant neck injuries that led to partial paralysis of the upper and lower limbs. Almost immediately his chest felt heavy and he became dyspneic. His pulmonary function values were as Vital capacity (supine) 650 mL Minute ventilation (supine) 6 L/min Respiratory rate (supine) 30 b/min PaO2 61 mm Hg PaCO2 47 mm Hg
